CARRIER FOR BRAlDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 447,108, dated February 24, 1891.

Application filed June 28. 1884- Serial No. 136,210. (No model.)

To all whom it may concern:

' cation.

The object of my invention is to provide an improved construction and operation of the spool-retaining pawls and tension-weights of carriers for braiding-machines.

The invention consists in the construction and combination of parts whereby the aforesaid object is attained, as will be hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 represents a side elevation of my improved braiding-carrier, the spool being shown partly in section. Fig. 2 is a detail sectional plan through the line a; a: of Fig. 1 as it appears before bending the lips of the vertically-sliding weight to fit it to its guidepost. Fig. 3 is a side view of the slide-weight, showing the manner of combining springtension with adjustable weight. Fig. 4 is a side view of the same, showing a modified manner of attaching extra weights upon the sliding weight. Fig. 5 is a partial plan view of the guide-groove for the carriers and of the ordinary stop-ring for stopping the machine when the thread breaks.

A is the base of the carrier, consisting, as usual, of upper and lower horizontal flanges a a, respectively, and a central web a connecting the said two flanges, which web works in the grooves L (see Fig. 5) of the machinetable M, in which the carriers travel, the flanges a at preventing the displacement of the carrier vertically. a is the downward projection or teat which enters the slots of the gear-wheels, by which successively the carriers are caused to travel in the zigzag grooves.

B is the upright guide-post for the sliding weight G, by which the thread is tensioned.

' The upper end of the sliding weight G is curved cross-bar g at the upper end and with astraight and rounded cross-bar g at the lower. end, the thread running, as usual, through an eye or hole 19 in the guide-post B, thence downand around the lower crossbar g, thence up to and through the eye bat the upper end of the guide-post B. This eye 1) projects laterally from the post B sufficiently to serve as a stop against the upperend 9 of. the weight G should the latter be raised high enough to strike it, and will thus prevent the weight G from getting off its guide-post, and thereby getting exchanged for the weight of another carrier.

The weight G has lips g upon its side bars g, which lips are formed in the casting in the shape shown in. Fig. 2, and are then bent inward over the beveled or rounded edges b of the post B, as shown by the dotted lines, thereby preventing the weight G from being removed laterally from the post B.

Later-ally upon the lower endof the weight G are formed pins or projections I. The object of these projections is the following: When the carrier travels in one of the outer curves of the guide-groove L, (and thus at a greater distance from the braiding-point than when it travels in the inner curve of the said groove,) it is evident that sufficient thread must be paid out to allow for said increased distance, in addition to the amount of thread yielded to the take-up. This causes the weight G to be lifted up by the stretching of the thread when the carrier travels in the outer curve of the groove L; but if the thread should break the weight would of course not be so lifted, but would remain at its lowest position. (Shown in Fig. l.) The projection I at the lower end of the carrier would therefore engage one or the other of the projections k on the ring K, (heretofore in use,) concentric with the table M, and thus cause the said ring to turn partially, said movement being transmitted to a suitable belt or clutch, or other device, (in a manner long known and generally used in braiding machines,) which immediately stops the motion of the braiding-machine, so as to enable the operator to discover the defect and mend the thread.

as bearings for the spool D, and at its lower end a shoulder c, which supports the spool. The upper end of the spool has cut into it the usual teeth to form the ratchet d, in which the pawl E engages to stop the revolution of the spool until the said pawl is raised out of contact with the teeth by the weight G.

I provide upon the upper end of the post a lug V, and pivot thereto a straight arm or pawl E, the long arm 6 of which engages the ratchet d and projects far enough to rest with its end against one of the guide-surfaces b of the post B, which entirely prevents any lateral deflection of the pawl. The said pawl is kept in contact with the ratchet by aspring F, fastened with one end to the butt-end e of the pawl E at the opposite side of and below the center of its pivot e, the other and lower end of the said spring resting in a socket in the upper end of the post 0. The spring F is merely of sufficient strength to keep the pawl to its work.

WVhen it is desired to remove the spool D and replace it with a new one, the pawl E is simply swung upward in line with the post 0 or in the position indicated in dotted lines in Fig.1 and the spool pulled off. The spring F, being then in its dotted position, acts on its leverage at the opposite side of the fulcrum, and consequently retains the pawl temporarily in the dotted position in Fig. 1. Thus it will be seen that even the pawl E remains stationary without being liable to get lost or exchanged, as is the case with pawls as formerlyconstructed. v The spring II adds to the weight to increase the resistance to the pull of the thread, and as the said resistance should be varied in proportion to the more or less heavy work or sizes of braiding made, I provide springs of different strengths, easily replaceable, one for the other, by simply ating weight G with pinsj, which may project horizontally, as shown in Fig. 4; but I preferably arrange them to project vertically, as in Fig. 3, (in which case only two pins, one on each side of the thread, need to be used,) and upon the said pins I attach weights J according as they may be needed.

By combining the weight J and the spring H, as shown in Fig. 3, any amount of tension necessary for the heaviest braiding work may be obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a carrier for braiding-machines, the combination, with the spool-post O and pawl E, the said pawl being hinged or pivoted to the spool-post C and adapted to engage the teeth of the ratchet (Z and to be placed in vertical line with the spool-post for the purposes stated, of the spring F, attached to the said spool=post and to the butt-end of the said pawl, and tending to retain the latter in either of the said positions, substantially as specified.

2. In a braiding-carrier, the slide-weight G, provided with pinsj, in combination with removable weigits J, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 10th day of May,

I. J. ALFRED FORNANDER.
